The output | The output masking in [[GPU/Internal_Registers#GPUREG_SH_OUTMAP_MASK|GPUREG_SH_OUTMAP_MASK]] influences how the registers starting at [[GPU/Internal_Registers#GPUREG_SH_OUTMAP_Oi|GPUREG_SH_OUTMAP_Oi]] will map to outputs in the shader. | ||
If an output is disabled in [[GPU/Internal_Registers#GPUREG_SH_OUTMAP_MASK|GPUREG_SH_OUTMAP_MASK]] it means that no slot in the [[GPU/Internal_Registers#GPUREG_SH_OUTMAP_Oi|GPUREG_SH_OUTMAP_Oi]] registers is consumed. | If an output is disabled in [[GPU/Internal_Registers#GPUREG_SH_OUTMAP_MASK|GPUREG_SH_OUTMAP_MASK]] it means that no slot in the [[GPU/Internal_Registers#GPUREG_SH_OUTMAP_Oi|GPUREG_SH_OUTMAP_Oi]] registers is consumed. | ||
